I already used version 8.6.0 which has fixed the error: NPE when thrift
field is nested ,but context is still null, why?

### Bug

- What happened?
If possible, provide a way to reproduce the error. e.g. demo application,
component version.
context is null, why?
code position:
ServerInProtocolWrapper#readFieldBegin()
@Override
public TField readFieldBegin() throws TException {
................
if (field.type == TType.STOP) {
Boolean haveCreatedSpan =
(Boolean)
ContextManager.getRuntimeContext().get(HAVE_CREATED_SPAN);
if (haveCreatedSpan != null && !haveCreatedSpan) {
try {
AbstractSpan span = ContextManager.createEntrySpan(
context.getOperatorName(),
createContextCarrier(null));
span.start(context.startTime);
span.tag(TAG_ARGS, context.getArguments());
span.setComponent(ComponentsDefine.THRIFT_SERVER);
SpanLayer.asRPCFramework(span);
} catch (Throwable throwable) {
LOGGER.error("Failed to create EntrySpan.", throwable);
